The United States is currently facing an early and severe allergy season in 2026, with spring allergies commencing sooner than usual across various regions. Areas in the Southeast, such as Georgia, have seen allergy season begin in late February, earlier than the typical early March start. Similarly, residents in the Southwest, including Arizona and California, are reporting increased allergy symptoms. Dr. Purvi Parikh, an allergist in New York City, points out that despite recent cold weather events, warmer temperatures are contributing to this early start. This aligns with previous years' trends, where rising temperatures have resulted in longer and more intense allergy seasons. The U.S. Department of Agriculture attributes these changes to global climate change, which has led to warmer seasons and extended agricultural growing periods, thus increasing pollen production.
